Yes, you can change the document that you have already submitted. In general, document resubmission possibly happens when:
1. Xendit internal team detecting the incomplete/incorrect requirements submitted on behalf of your account during the KYC/verification process. Hence you'll receive notification via email, WA (ID), or Viber (PH) related to the details of the missing docs. In this context, please follow the detailed guidance here to update your documents
2. Merchant desire to change the submitted requirements before the Xendit internal team notify them to do so. In this situation, the requirements changes can be done directly via the dashboard. Simply login into your account and directly replace the documentation in the activation form. However, if you are unable to proceed, please feel free to reach our CS via email@example.com.
